Since the ChatGPT-5 update, the conversation window becomes slow and unresponsive much faster than before. What used to happen only after hours with GPT-4 now occurs quickly, forcing constant browser refreshes just to receive new messages or code. This is not a hardware issue — I’m on a Ryzen 9 5900X, 16GB RAM, and an RTX 2080 Ti. The update degraded reliability and usability. With so many promises, the platform should at least deliver stable performance. Right now it feels frustrating and close to unusable.
The desktop and Browser client are awful. They grind to a halt as they both appear to try and render the entire conversation all the time. Unlike the mobile client. The desktop client does take advantage of any power on a PC including GPU
I am noticing a consistent failure with CHATGPT 5. Initially I used 4o to overcome this but now looks like that is also failing. I am having a feeling GPT is slowly unlearning things. It also appears at a critical juncture GPT repeatedly failing giving an impression that it seems purposefully done by OpenAI. While I reached out to support they provide a very standard privacy response without proper explanation. No transperancy on how many deep research allowed for any of the plans (I am having pro) and suddenly they say it is running on ligher version. There is no way to make any payment to get some more deep research too.. Sorry no transperancy.. may be consider changing your name to ClosedAI instead of OpenAI.
I am seeing lot of issues reported by lot of people. I had not seen even one reply from OpenAI. Are they really looking into these issues and resolving them. I had decided to cancel the subscription. Compared to the chatgpt pro Gemini free subscription is giving much better response. Totally disappointed on the degrade of performance.
Im experiencing the same, chatGPT kills my browser, tried Chrome and Edge. The repsonses are soooo slow, the window freezes mid response, I have to reload the window a few times, re-start browers window, even re-start my PC. Took hours to do something that should only take minutes. Its impossible to work like this. I just bought Claude to try it out and its fantastic. Was working on some app coding and ChatGPT couldnt get bugs out after hours, Claude figured it out in 2-3 runs.
Same problem.. ChatGPT is more or less unusable now… getting frustrated as paying customer.
Some responses takes like 2 to 10 minutes to even show up for me… Every thing just freeze!!!
The windows client is a joke… the quality is not what I expect. its better on my Mac and Iphone.
Basically unusable for any conversation of significant length on Windows, either in a browser or the “app”, which is just a browser wrapper anyway. Runs fine on my very average phone (Motorola Moto) so having to use scrcpy to get the Android phone display onto my PC screen.
The experience is not just poor, it is absolutely unusable. That it runs fine on a low power device (phone) but at only a few per cent of the speed on a well specced desktop indicates to me that the code/framework used is entirely inappropriate.
Its completely unusable these days, why am i paying for this, its literally unusable, i need to close the browser tab , reopen, wait for answer , if it appears, ask the next question, rinse and repeat.
Same for the app.
Somewhat better on my phone?
I have the same problem. Web browser (Brave), Windows 11 laptop. Plus account. No problem with responses. Input box freezes for up to 3 seconds as I’m typing then catches up with me. Scrolling through the conversation also freezes then catches up. I’ve had this problem for several weeks.
Any one found a solution to this bottleneck issue, it’s frankly quite annoying. i am trying to code and you can guess the conversation get’s heavy real fast, but it’s getting worst and worst. i tried to clean the cache, turn hardware acceleration on, nothing changes. but one night it got real better olny to be back to crap in the morning. sometimes it feels to me likes something pulls more juice than me, maybe someone with a pro account doing massive math or something more neferious like logic loop or hackers trying to crash the whole thing down. i don’t know but it sucks and i hope open ai knows about this issue and are working on it.
I’m having the same issue on a laptop with a 5090, 96gb RAM, and a Core Ultra 9 275HX.. There is no reason that it should be grinding to halt like this n a local level and I get it with Chrome/Edge/Waterfox and the Desktop app. This happens in a relatively short conversation also.
It’s a relief to know it’s not just me. I haven’t even been using GPT to code for some time now, usually just short-form and simple questions and answers, yet it struggles. My hardware isn’t an issue, it could be the only tab I have open, but GPT forces me to refresh my browser and even then it’s questionable. Half the time after I ask a question, Edge gives me a notification the website can’t respond (forcing another refresh) - all things everyone else seems to be saying too. I’d like to think maybe it’s a bug and they’re working on it, but with how widespread use has become, their servers may just be very overwhelmed, therefore slow.
On another note, did they remove the option for the free membership to choose which model to respond? Silly that I haven’t tried different models to see performance, but now that I went to look for the option under my most recent response received, it isn’t there. Maybe the option moved in the UI?
Yes, unusable, and essentially for the same reason. The code is super complicated and totally inefficient. It’s not ChatGPT LLM inference that’s slow, it’s the absolutely awful bad app code. Most of this nightmare is because they are trying to lock people out of scripting on the chatgpt app I assume, and also, they go with stupid framework bloat instead of making something simple and responsive.
I actually have a somewhat workable solution. It’s still ridiculous, but it works somewhat.
I post my next prompt, and I only wait so long as to see it actually has received it and starts working (usually thinking nowadays). I then close that browser tab altogether, after copying the URL from the address bar.
I open a new browser tab and paste that URL into its address bar, but I wait a bit before actually navigating there.
If I want, I can use my android phone app to monitor if it finished responding, or I just wait until I am ready.
Once it has finished responding, the page loads fairly quickly and I can see the response, and I am ready to write my next prompt and proceed in that same way as itemized above.
When the thread does really get too long, I have asked it to give me a final summary in the form of a prompt for a new thread, in a cut&pasteable plain text box. Then I copy that prompt, and create a new thread (attaching whatever work files might now be involved.
